Oh heck ...what a drive combo!
You have definitely no mixing ...one of the OLD TRICKS ...pre electrickery mixing... was to remount the transmitter stick pod by rotating it 45 degrees.
I'll have a think about your VERY STRANGE drive combo.
Of course, my mistake. I think I need a very early bedtime today i'm not thinking straight at all. I just made an Ar$e of explaining it to someone else too.
It's going to be a pain in the Ass to setup...like you have it....and maybe impossible.
Go for the XL in combined mode on one side ....and duel Electronize off a Y lead on the other.
You then have the possibility of altering the servo travel TRV ADJ to compensate for drive side speed differences.
I'd also make sure that the XL calibration is factory reset via the calibration jumper BEFORE attempting to match the drive sides.

The motors are all the same aren't they? ....Please say yes!
Haha, don't worry Tony, it happens to us all. I should be in bed but can't be bothered shifting all my tools off it
@Woody: yeah it's certainly a bit different for a drive system! There's reason to the madness though. If the mixing in the transmitter doesn't work I think we talked about just connecting an external mixer to the Electronize controllers for the back wheels and using the built-in mixing of the XL for the front wheels.
If all else fails though, there is always the jaunty-angle transmitter method as you mentioned
EDIT: Just noticed your above suggestion Woody. The robot is now back in Tony's hands so will have to see if he can try that out and what the results will be.
Can't hurt to try .... but it might be doomed to failure...getting the two different ESC's to match speed outputs is going to be ...Ummmmm ..Challenging!we talked about just connecting an external mixer to the Electronize controllers
I don't want to say too much for fear of making myself look more stupid after my last statement haha.
The only thing about that setup you suggest Woody that I noticed today when we were testing it with wheels off the ground was the XL and Electronize's respond slightly differently to stick movements and that might cause it to veer off to the side, especially when accelerating from stopped or slowing down to a stop.
I'm glad we're trying it on the day of the champs thenOriginally Posted by woody
Yeah, matching the wheel speeds will be a bit tricky, suppose the best way to judge will be by the sound of the motors. The idea of the Electronize controlling the rear wheels instead of the front was that they're less precise than the XL and since the back wheels are more likely to be skidding and (potentially?) wheel spinning when turning, any speed differences would be barely noticeable or not have a profound effect on the robot's driving characteristics.
I guess time, and testing, will tell though.
The motors are all the same Woody yes. Sorry I missed that bit of your response until now.
